Dmitry of Tver

Dmitry "the Fearsome-Eyed" of Tver (1299-15 September 1326) was the Grand Duke of Tver from 1318 to 1326 and the Grand Duke of Vladimir from 1322 to 1326. He launched a rebellion against the Mongol Empire's Golden Horde, but it was brutally suppressed in 1318.

Biography
The son of Mikhail of Tver and Anna of Kashin, Dmitry of Tver assumed the title of Grand Duke of Tver in 1318. He continued his father's rivalry with the Grand Duchy of Moscow over the Grand Duchy of Vladimir, whom the two nations' rulers wanted to assume the title of ruler of. The title also meant that the ruler would be the Mongol Empire's tax collector, giving the Grand Duke power over the other princes of the Kievan Rus.

Dmitri and his brother Alexander fought a series of wars with Prince Yury Danilovich of Moscow to avenge the murder of his father in 1318, and they intrigued him against the Golden Horde. Dmitry became yarlik, the tax collector, but after he had Yury assassinated in 1325, he was held responsible for the chaos and executed in Sarai (Selitrennoye, Astrakhan).
